Valsir Tropea S Inwall Cistern (Pneumatic)

Valsir Tropea S: The World’s First Soundproof, Ultra-Slimline Cistern

The Valsir Tropea S is the gold standard of in-wall cisterns, combining Italian elegance with record-breaking performance. At just 90mm deep, it is engineered specifically for standard Australian wall cavities, making it the most popular choice for modern renovations and new builds where space and silence are paramount.

As the exclusive Australian supplier for Valsir, we provide the genuine Tropea S—the only cistern in the world designed with a patented soundproofing plastic compound.

The Revolution of Silence 

In-wall cisterns can often be noisy through shared walls. The Tropea S solves this with advanced acoustic engineering:

• 5x Quieter: Laboratory tests prove the perceived noise from a Tropea S is five times lower than standard cisterns on the market.

• Acoustic Plastic Compound: Crafted from a specialized formula that absorbs vibrations and dampens the sound of rushing water.

• ISO EN 3822 Certified: Rated Class I for silence (the highest possible rating), making it the premier choice for master ensuites and apartment living.

The Slimline Specialist: 90mm Depth

Many concealed cisterns require deep wall build-outs. The Tropea S is designed to fit into a 90mm cavity, allowing for a seamless, flush-to-wall finish without sacrificing bathroom floor space. This slim profile makes it the “architect’s favorite” for maximizing room volume.

Key Features & Benefits

• Universal Compatibility: Patented flush valve technology ensures a perfect clean for all toilet pans, including the latest rimless models.

• Limescale Resistance: Internal components are made from high-performance technopolymers that prevent calcium buildup—perfect for Australian hard-water regions.

• Water Efficiency: Easily adjustable flush settings (6/3L, 4.5/3L, or 4/2L) to meet and exceed Green Building and WELS requirements.

• 100% Pre-Assembled: Arrives fully water-tested and assembled, ensuring a fast and error-free installation for your plumber.

The “No-Flexi” Design

Like all modern Valsir systems, the Tropea S eliminates the internal flexible hose. By using a direct-feed vertical inlet, the system removes a common failure point and eliminates the high-pitched “whistling” often found in cheaper valves.
